Competitor Keyword Gap Analysis: Finding Terms Your Rivals Rank For
Your competitors have already done some of your keyword research for you. Every page they rank for is evidence that a search exists, that Google rewards a certain kind of page for it, and that the topic matters to your shared audience.
A keyword gap analysis compares the keywords your site ranks for with those of a few competitors, and highlights the ones they have and you don't. Done carefully, it produces a content plan grounded in real results instead of guesses.
Step 1: Choose the right competitors
Your business competitors and your search competitors are often different. A Jaipur handicraft exporter might compete in business with three local firms, while in search it competes with marketplaces, craft blogs and a Delhi-based store.
To find search competitors:
- Search your five most important keywords and note which domains appear repeatedly.
- Use your SEO tool's "competing domains" report, which lists sites with the most keyword overlap.
- Exclude sites you can't realistically emulate, like Amazon or Wikipedia, unless you only want ideas.
Pick three to five competitors of a similar size or a little larger. Comparing a new site against a giant mostly produces an unusable list.
Step 2: Run the comparison
Most paid SEO tools have a keyword gap or content gap feature. Ahrefs, Semrush and several others offer one. You enter your domain and competitors, and the tool shows:
- Missing: keywords all or most competitors rank for and you don't
- Weak: keywords where you rank, but lower than competitors
- Shared: keywords where you all rank
- Unique: keywords only you rank for
Start with "missing" and "weak". Set a filter so that competitors must rank in the top 10 or 20; otherwise you'll get thousands of terms where nobody ranks well.
Without a paid tool, you can do a rough version manually: list competitors' main pages from their sitemaps or menus, search their key topics, and note what they cover that you don't. It's slower but still useful.
Step 3: Filter out noise
Raw gap exports are messy. Remove:
- Competitor brand names and product names
- Keywords outside your business ("careers", "login", unrelated topics they happen to cover)
- Terms with intent you can't serve
- Locations you don't operate in
What's left should be keywords a page on your site could genuinely serve.
Step 4: Group into topics
Many keywords in the export will be variations of the same need. "Blue pottery vase", "jaipur blue pottery vase", "blue pottery flower vase" all point to one page. Group them by intent, then look at the total opportunity per group rather than per keyword. The keyword research guide covers grouping in more detail.
Step 5: Check what's actually ranking
For each topic group, look at the competitor page that ranks:
- What type of page is it? Category, guide, tool, product?
- How thorough is it?
- How many referring domains does it have?
- How old is it, and is it maintained?
This tells you what you'd need to build and how hard the competition is. A competitor ranking with a thin 400-word page and no links is an easy target. One ranking with a heavily linked, detailed guide needs more effort and probably some links. Our competitor backlink analysis guide covers the link side.
Step 6: Prioritise
Score each topic on three things:
- Business value. Would this traffic lead to enquiries, sales or the readers you want?
- Difficulty. How strong are the ranking pages compared with your site?
- Effort. Can you update an existing page, or do you need something new?
Topics high on value and low on difficulty and effort go first. Topics where you're already ranking on page two (the "weak" list) are usually the fastest wins, because the page exists and needs improvement rather than creation.
Step 7: Build better pages, not copies
The point is to find the topic, not to copy the competitor's page. Look at what they missed. If their guide to "blue pottery care" is generic, yours can include photos of real damage, what actually cleans glaze safely and where to get repairs done in Jaipur.
Your page should be the one a reader would choose if both appeared side by side.
An example
A small SaaS for appointment booking compares itself with three competitors and finds gaps around "salon booking app", "clinic appointment software" and several "how to reduce no-shows" queries. It already ranks on page two for "online booking for physiotherapists". The plan:
- Improve the physiotherapy page (quick win)
- Write a practical no-shows guide with templates (informational, links to product)
- Create industry pages for salons and clinics with genuinely different features and examples
How often to repeat it
Competitors publish new content and rankings shift. Repeating the analysis every three to six months catches new gaps and shows whether your previous work closed the old ones.
A place to start
Pick your three closest search competitors and run a gap report with a top-10 filter. Export the missing keywords, delete anything irrelevant, and group the remainder into topics. Choose the two topics where you already rank on page two and improve those pages first.
